The only cartridges that uses .222" bullets are .22 rimfire and the .22 Rem Jet. If you are going to load .222 Remington this uses .224" bullets.

If you have an old .22 Hornet, made back in the 1930s, and it was made with a .22 rimfire barrel go ahead and shoot the .223 bullets! If you have a factory Hornet more recent than the 1950s it will have a .224 barrel too!

And, while we are at it, the only .223" Hornet bullets I am aware of is 40-45 grain. If you have 55 grain bullets they are .224" too. It may seem counter-intuitive to you but virtually all of the various .22 caliber rifles from the .222 Rem, .223 Rem, all .224s, and .225 Winchester use .224" bullets, regardless of what the cartridge is named.

Before you begin reloading ammunition you need to do a lot more research on the subject before you hut yourself!
